1. (a) Initial fill water for post-10/01/99 and pre-10/01/99 pools and spas. The water supply used to fill a post-10/01/99 or pre-10/01/99 pool or spa shall be from a potable water system that meets applicable standards of 30 TAC, Chapter 290, Public Drinking Water, Subchapter D, Rules and Regulations for Public Water Systems, or meets the approval of the department or local regulatory authority, or is from a pre-10/01/99 pool's water that meets or exceeds all relevant conditions in this standard.
2. (b) Make-up water source for post-10/01/99 and pre-10/01/99 pools and spas. In a post-10/01/99 or pre-10/01/99 pool or spa, water added to maintain the pool or spa water level, water used as vehicle for disinfectants or chemicals, and water used for pump priming shall be potable water from a water system meeting applicable standards of 30 TAC, Chapter 290, Public Drinking Water, Subchapter D, Rules and Regulations for Public Water Systems or local regulatory authority or shall be water from the pool or spa itself.
3. (c) No direct connection to wastewater system for post-10/01/99 and pre-10/01/99 pools and spas. In a post-10/01/99 or pre-10/01/99 pool or spa, no direct mechanical (hard) connection shall be made between the pool or spa, chlorinating equipment, or the system of piping for the pool or spa and between the sanitary sewer system, septic system or other wastewater disposal system.
4. (d) Fill spout for post-10/01/99 pools and spas. An over-the-rim spout, if used in a post-10/01/99 pool or spa, shall be located under a diving board, adjacent to a ladder, or otherwise properly shielded so as not to create a trip or other hazard. Its open end shall have a secured soft pliable end (for example, a short section of a rubber hose) to prevent injury to patrons and shall not protrude more than 2 inches beyond the edge of the pool or spa. The end of the soft pliable outlet shall be separated from the maximum possible pool or spa water level by an air gap at least two times the diameter of the pipe. Other methods for addition of water to the pool may be used as long as cross-connections control and other safety considerations are adequately addressed.
5. (e) Fill spout for pre-10/01/99 pools and spas. An over-the-rim spout, if used in a pre-10/01/99 pool or spa, shall have a secure soft pliable end (for example, a short section of rubber hose) to prevent injury to patrons and shall not protrude more than 2 inches beyond the edge of the pool or spa. The end of the soft pliable outlet shall be separated from the maximum possible pool or spa water level by an air gap at least two times the diameter of the pipe.
